I'm taking that this happens when installing Geany. This isn't a Geany bug though. This warning appears if the refreshing of the package index went bad. This usually means that there is a transient error in the Ubuntu mirror you are using. Running "sudo apt-get update" in the terminal, or opening Update Manager and clicking "Check" should fix this.
